Compiler's 24 x great-grandmother

  Research Notes:

She was presumably the unnamed daughter mentioned in the following charter. Gérard Bishop of Cambrai confirmed the foundation of Aymeries priory by "Ermengardis de Mons...cum filiis suis...et filia" by charter dated 1088, subscribed by “...Gosuini de Montibus et Isembardi filiorum Ermengardis”.

The Annales Cameracenses record the death "II Kal Apr" in 1145 of "castellana Heldiurdis". The necrology of Béthune Saint-Barthélemy records the death “II Kal Apr” of “Heldiardis de Oisy”. 2
